According to one embodiment of present invention, Fig. 2 is timing failures diagnostic flow chart, i.e., timing failures diagnostic task is interior
Portion's implementation flow chart.Timing diagnostic task is an executable program, is triggered and is executed by timed task.Internal implementation process is as follows
It is described.Available diagnostic task is first checked for, i.e. diagnostic program class name whether there is, and diagnostic task information is safeguarded in timed task
It inputs, and is stored in the diagnostic task table of database in function, diagnostic task table record is in direct searching database herein
Can, if it does not exist, then prompt establishes diagnostic task and exits Current Diagnostic task in log information.If there is available
Diagnostic task information then continues checking for available diagnostic model and whether there is, diagnostic model information preservation in database table, by
Diagnostic model maintenance function typing.If there is no available diagnostic model information, then diagnosis is established in prompt in log information
Model simultaneously exits Current Diagnostic task.If there is available diagnostic model information, then continuing checking for available model result is
No presence, model result are the model information preserved after model training and training result.If available model result is not present,
Preservation model result is then prompted in log information and exits Current Diagnostic task.If there is available model result information,
It then continues checking for Hydropower Unit state recording whether there is, if it does not exist, then prompting typing set state in log information
It records and exits Current Diagnostic task.If there is Hydropower Unit state recording, then the available of the Hydropower Unit to be diagnosed is recycled
Model result records, and model result record includes model training file and model information, by reading the first row operating parameter letter
Breath obtains model training file content, and tissue generates Hydropower Unit "current" model operation data accordingly, and generates csv to be predicted
Data file, according to model relevant information and file to be predicted, calling model anticipation function carries out fault diagnosis, finally to prediction
As a result it is analyzed and is recorded, i.e., each prediction result compared with the state encoding in set state information, if prediction knot
Fruit is consistent with state encoding, illustrates that the prediction result of the Hydropower Unit is exactly the meaning that the state encoding represents, checks the unit
In status information whether processing is true, if it is true, need result information being recorded in idagnostic logout result, believe
Breath includes Diagnostic Time, Status Name, suggestion takes measures, generating state reason does not record then if NO.Primary pre-
It surveys in result, first is only retained when there is identical prediction result, if prediction result does not appear in set state information
Meeting record log information, and prompt unit status information imperfect, typing asked to be encoded to the set state information of prediction result.
According to one embodiment of present invention, Fig. 3 is that timing failures predict flow chart, i.e., timing failures prediction task is interior
Portion's implementation flow chart.Troubleshooting Flowchart is similar with failure predication flow, and same place is not repeating.Just start check be
Available prediction task, i.e. Prediction program class name whether there is, and then continue to check diagnostic model, model result, set state
Etc. information whether there is.Cycle will predict the model result of Hydropower Unit if all existing, and per diem, week, unite for the period moon three
Average value of corresponding nearest 60 cycle phases of meter with the Hydropower Unit operational parameter data under operating mode.Then time series is used to calculate
Method, 3 week after predicting 60 day, week, the moon using the addition model of long-term trend, seasonal move, cyclical variations, erratic variation
The data of phase.Prediction result is preserved into csv data files to be predicted, according to model relevant information and file to be predicted, is adjusted
Fault diagnosis is carried out with model prediction function, finally prediction result is analyzed and recorded, analysis result is stored in prediction knot
In fruit information, for predicting record queries functional inquiry.
It should be noted that and understand, in the case of the spirit and scope required by not departing from the claims in the present invention, energy
It is enough that various modifications and improvements are made to the present invention of foregoing detailed description.It is therefore desirable to protection technical solution range not by
The limitation of given any specific exemplary teachings.
